Battery type AA/NiMH/Eneloop in K-x, K-r, K30 K50, K500 as well as *ist/K100/200/2000

Because (sadly?) we have no sub-forum for the K-x I write this here in the sub-forum for the K-r:

Many had problems with the type of battery, depending on:
1. different types of AA NiMH: Ricoh USA sold the K-x with Energizer-AA's (as far as I remember, correct me if I am wrong)
In the European Union it were Energizers as well in the beginning but soon they changed for Panasonic Eneloops for a reason.
2. different types of batteries: Ni-MH or Li-Ion (K-r, K30/50/500)
3. correct handling of menu and or swap between different battery-types

Ricoh Switzerland and Ricoh Germany had a particular page for those problems relating the the K-x and this goes as much for the other mentioned cameras which allowed different battery types (so as well for the K100D, K200D, K110D and K-m/K-2000 as well as all *ist bodies!)

Basically Ricoh mentioned that the discharge-curve of AA's depends very much on type and can be either pretty even or steep.


With older type AA's the K-x gave the message, that the battery would soon be empty.


For the K-x (and all others mentioned) being able to measure the actual charge it has electronics onboard to automatically recognize the type of the battery.


In the menu factory-setting is on AUTO.

The camera will "remember" the type of battery used for 1 minute.

If one uses different battery types, this can lead to wrong measurements and thus wrong state of charge.

Therefore one should either set the type exactly in the menu


or...

... wait 1 min. after one changed to a different type.


This waiting time will allow a reset of the memory (of the previous type used).


If one does not wait,the memory stores the wrong type!

Also it is important to realize that NiMH's only have their full capacity after repeated charge and discharge!

Ricoh explained this in detail with this test-method:

- place batteries into the camera
- state of charge is shown now "orange"
- leave camera unused without switching off: Camera goes into Stand-By:
Shutterreleasebutton pressed: state of charge now "green"
- Set in menu on JPEG, 2MP and 1 star, AF switched off
- do continuous serial-shots
- after about 670 shots the battery state will show "orange"
- short break, battery state goes back to "green"
- after another 1300 shots stop
- Change to "video-mode":
- after 3 minutes taking a video battery state "orange", but after a few seconds later back to "green"
- another 12min video recording. Battery state changes between "orange and green"
- Another 16,5 min. video recording, thermometer warns overheating now and battery constant "orange" now.


So after 1300 shots and 25 min. video recording in sequences of 1,5 min each this test was finished.
After another 30 min. 1x more sequence of 1.5 min. video was possible: Eneloop AA's now complete discharged.

This test took about 4 hours but showed how good new Eneloops really are

A good page on Eneloops and different measurements/comparison and of the different generations
can be found HERE

The original message in German by Ricoh one finds HERE

Change of battery type in the menu as far as I remember:
- Wrench-symbol 3/battery-type: One can chose:

- AUTO
- Lithium
- Nickel-Metallydrid (NiMH)
- Alkali Select "Ni-MH"

Impressive numbers, I tried 2 sets of eneloop on my K30 and never had those numbers. With auto or Ni-MH I never had a better results the original lithium battery the camera gives up long before the eneloop are exhausted. The battery sets work great on flash and put out more than 2500mA on a 0.5A load.
I'm now trying this with better results that the eneloop so far.

Even with emeloops I never reached 500 shots per battery charge on my k-x.

Depends of course on a few other factors as well:
- capacity of Eneloops
- age of Eneloops
- how is the camera used, i.e. a lot with LV (liveview) (which drains a lot), video (which is in LV mode and drains even more)

The new type Eneloops (PRO or XX with 2500mA) are really great.

What I wrote about the cameras memory for which battery is used, i.e. when changing type of battery and waiting 1 min.

or change it in the menu goes as well for K30/50/500 when used with AA-adapter instead of Li-Ion!

The Ricoh-Germany link which I gave in the first post is down.
Here is the original pdf document in German.

Good news everyone - who, like me, love the old K200D and other CCD cameras.
There is now a great solution to the AA battery problem:
Rechargeable AA Li-Ions are here !
Although a bit expensive (I paid around 35-40 USD equiv. here in Norway for 4 pcs with micro-USB 4-way charging cable),
they work as promised, and much better than Alkalines, NiMhs or Lithiums.
I bought them here (They are called Pale Blue):

Thanks for the link.
At the moment I'm using eneloops in my *istD cameras with no problems, several hundred exposures per charge and excellent shelf life.
It would be interesting to know what the self-discharge characteristics are like.
I can expect my eneloops to hold a usable charge for well over a year, so, for the asking price, it'll need to be considerably better than that!
At a price around three times the current cost for eneloops I'll not be buying any anytime soon, but as the web-site doesn't accept my post code I can't order any anyway

Hello kypfer & others.
The link was merely to show some images of the Li-Ion battery.
As this is a Scandinavian store I hope you can find them in some other online store closer to where you live or maybe similar types.
I am just glad these now are being made and wanted to share the good news.
Similarly these Eneloops you are talking about are not available here.
Be safe!
Lars

Norway is next to Sweden, homecountry to Ikea.
Ikea sells the LADDA
which is the strongest Eneloop AA made by Panasonic for Ikea.
It has a capacity of 2450mA and can be recharged 1000x
HERE a very thorough test.

Of course, the Li-Ion AA's are interesting but with 1560mA they can't compete for capacity.

What I don't like at all is the sole charging via USB!
Good cells need a good charger and Li-Ions need a special charger different to NiMH's.

For the price of the PaleBlue's you'll get 4 x 4set of Lada's Ladda's
or 2 sets + a decent charger.

I have NiMH's sold in Switzerland under a Suisse label but actually they are Eneloops. They last and last and last.

Thanks for the link for IKEA's
LADDA batteries.
(LADA is an East European car).

Up till now, I have tried a lot of high capacity NiMh batteries in my K200D with limited success.
Anyway, I have ordered 8 of those now, and a charger.
So when they arrive I shall be able to compare them to the Li-Ions.
Still sceptical as they, (LADDA NiMh) are only 1.2 V
Thank you
Lars

Ladda are made by Panasonic and 1:1 the same as ENELOOP's which Ricoh Germany particular recommended.
The charger by Ikea is not the best, chargers which control each cell individually and cut of charging when full charged and change over to "keep the charge"
(not very important because Eneloops keep it anyway) is essential.

One has to invest a bit more but it is worth it.
The LADDA's and Eneloops work with 1.2V because it is not so much voltage but current which counts.
This has been proven very well when people use Eneloops for the K30/50/500 with the adapter.
Heavier but very reliable.

In the past I had no other NiMH's of comparable quality but now AA's pop up claiming low discharge such as EBL.
I cannot say anything about them, but as far as I know Panasonic and Fujitsu are the real ones, Ladda's being made by Panasonic.
Panasonic ones are made in China, Fujitsu the only ones with Japanmade cells.

I use both of them.
